compress

[Unix] vt. When used without a qualifier, generally refers to crunching of a file using a particular C implementation of compression by Joseph M. Orost et al. and widely circulated via Usenet; use of crunch itself in this sense is rare among Unix hackers. Specifically, compress is built around the Lempel-Ziv-Welch algorithm as described in "A Technique for High Performance Data Compression", Terry A. Welch, "IEEE Computer", vol. 17, no. 6 (June 1984), pp. 8-19.

compress definition


1. To feed data through any compression algorithm.
2. The Unix program "compress", now largely supplanted by gzip.
Unix compress was written in C by Joseph M. Orost, James A. Woods et al., and was widely circulated via Usenet. It uses the Lempel-Ziv Welch algorithm and normally produces files with the suffix ".Z".
Compress uses variable length codes. Initially, nine-bit codes are output until they are all used. When this occurs, ten-bit codes are used and so on, until an implementation-dependent maximum is reached.
After every 10 kilobytes of input the compression ratio is checked. If it is decreasing then the entire string table is discarded and information is collected from scratch.
